I usuallu use powermaster 50% or 60% and I get it at Hobby People. Be careful what you are using it in. It can destroy a motor that was not designed for it. You average car or monster truck will rock for a few minutes alright, then rock no more!!

I just got a Miss Bud with a .18 air/water cooled engine that the guy was running 50% in and it has been rocking for a long time. I'm just looking for more speed and power.

Red Max, Byron's (I have some of their 60% but haven't used it yet) and most others that make boat fuel have it that high. I have a local guy that can mix up whatever I want, Brian Cooper of Cooper's Custom Blends. He doesn't advertise in here that he's a fuel maker but he can be found on the Fuel forum as Fuelman.
I myself don't usually go over 50% in my boats because as the nitro percentage goes up, it makes it harder to get a good needle setting, especially if you live where the weather gets hot in the Summer.

Before you waste $35 to $40 on a gallon of fuel, why don't you first determine if the engine is set up to use the high notro? To many people think that putting a tuned pipe on an engine and pouring nitro to it will make a powerful engine. Typically, the low end engines that they put in those RTR boats are not designed for a pipe and high nitro. Port timing and head clearance are critical factors in using a pipe and high nitro. Do your homework first, then proceed.

Will I notice a difference from 20% to 35%?

I would doubt it. I equate it to putting high test gasoline in a Ford Escort. The engine is not designed to run on high test so the increase in performance is negligible. On the other hand, an engine designed for high test will come alive with the right fuel.

Example, I have a K&B 3.5 engine in my outrigger hydro. I run it on 25% nitro. I've tried it on the 60% that I run in my Wild Thing with a MAC .21. I can't tell the difference. The MAC .21 is designed to run on high nitro whereas the K&B is not.

The same goes for putting a tuned pipe on an engine without attention to the engine timing. The pipe divergant/convergent connection has to be set at a specific distance from the engine. Typically measured from the glow plug. If it's not set correctly it can steal power rather than increase power. In addition, the port timing in the engine has to be designed to work with a pipe. Otherwise you have nothing but a long skinny muffler on the engine.

I don't profess to be an expert at this game but many years of boat racing has taught me a lot. The trick is to pay attention to the guys with experience. You can usually pick them out over the guys that are just blowing hot air.

I will be necessary to change the head clearence if you are going up to 50 or 60%. A higher head clearence is necessary to avoid detonation and over heating. You can typically go up about 10% in nitro content from what the engine was designed to use without any changes. Say from 20 to 30%. No changes needed, but from 20-60%. You are definately are going to need to go up in head clearence .010-.020.

I think you would notice a difference in going from 20 to 35%. It is definately noticable in my NTC3. When I switched fom 20 to 30%, the increase in acceleration was very noticable. Pipe length would laso likely change - longer.

I find it hard to believe an .18 rtr engine with no modifications, will rock for very long on 50% nitro. It might rock for a few funs, but will likely grenade soon after.
